Description
Die Erfindung betrifft eine Vorrichtung zur Halterung der vorzugsweise aus Kunststoff hergestellten, parallel im Abstand zueinander verlaufenden Rohre eines im Gehäuse eines Wärmeübertragers angeordneten Rohrbündels.The The invention relates to a device for holding the preferably made of plastic, running parallel spaced pipes one in the housing a heat exchanger arranged Tube bundle.
Derartige Halterungen sind in einer Vielzahl von Ausführungen bekannt, wobei jedes Rohr relativ zu mindestens einem seiner benachbarten Rohre durch mindestens einen, zumindest einen Teil seines Umfanges berührenden Abstandshalter lagegesichert ist. Diese Abstandshalter bestehen entweder aus einander kreuzenden Streben oder Bändern, die an einem gemeinsamen Rahmen befestigt sind. Diese Rahmen sind entweder am Gehäuse des Wärmeübertragers befestigt oder mittels der Abstandshalter auf den Rohren angeordnet. Während sich beim erstgenannten Fall aufgrund der unterschiedlichen Wärmeausdehnungskoeffizienten des Materials einerseits der Rohre und andererseits des Wärmeübertragergehäuses schädliche Relativbewegungen zwischen Rohren und Abstandshaltern ergeben, wird im zweiten Fall eine aufwendige Führung des mit den Rohren verbundene Rahmens relativ zum Wärmeübertragergehäuse erforderlich.such Mounts are known in a variety of designs, each one Pipe relative to at least one of its adjacent pipes at least one, at least part of its circumference touching Spacer is positionally secured. These spacers consist either of intersecting struts or ribbons attached to a common Frame are attached. These frames are either on the case of the heat exchanger attached or arranged by means of the spacers on the tubes. While in the former case due to the different thermal expansion coefficients the material on the one hand the pipes and on the other hand the heat exchanger housing harmful relative movements between pipes and spacers, in the second case an elaborate tour the frame connected to the tubes relative to the heat exchanger housing required.

Ausgehend von diesem bekannten Stand der Technik liegt der Erfindung die Aufgabe zugrunde, eine Halterungsvorrichtung der eingangs beschriebenen Art derart weiterzubilden, dass sowohl schädliche Relativbewegungen zwischen Rohren und Abstandshaltern als auch aufwendige Führungen für die abstandshaltertragenden Rahmen vermieden werden.outgoing From this known prior art, the invention has the object based, a mounting device of the type described above To develop such a way that both harmful relative movements between Tubes and spacers as well as elaborate guides for the distance-supporting Be avoided.
Durch die Lagesicherung der Rohre untereinander ausschließlich über Abstandshalter, die jeweils mindestens zwei Rohre miteinander verbinden, und durch die Befestigung dieser Abstandshalter auf den Rohren ausschließlich durch Klemmkraft, die zumindest das Eigengewicht jedes Abstandshalters kompensiert, kann auf die Verwendung von Rahmen verzichtet werden. Es erübrigen sich somit aufwendige Führungen für derartige Rahmen. Außerdem werden Relativbewegungen zwischen den Rohren und den Abstandshaltern vermieden, weil die Abstandshalter durch Klemmkraft auf den Rohren befestigt sind, so daß die Abstandshalter sich bei temperaturbedingten Längenänderungen der Rohre mit diesen innerhalb des Wärmeübertragergehäuses bewegen. Mit den Rahmen entfällt auch eine zusätzliche Belastung der Rohre durch das Gewicht der Rahmen. Neben einem verringerten Bauaufwand ergibt sich schließlich eine einfachere Montags der Abstandshalter.By the position securing of the pipes to each other exclusively via spacers, each connect at least two pipes together, and by the attachment of these spacers on the pipes exclusively by Clamping force compensating at least the weight of each spacer, can be dispensed with the use of frames. It is unnecessary thus elaborate guides for such Frame. Furthermore become relative movements between the pipes and the spacers avoided because the spacers by clamping force on the pipes are attached so that the Spacers are at temperature-related changes in length of the tubes with these within move the heat exchanger housing. With the frame is deleted also an additional one Load the tubes by the weight of the frame. In addition to a reduced Construction costs finally arise a simpler Monday of the spacers.
Gemäß einem weiteren Merkmal der Erfindung umfaßt jeder Abstandshalter mindestens zwei Klemmstellen, die jeweils schalenförmig mit einem Umschlingungswinkel > 180° ausgebildet und durch einen Steg miteinander verbunden sind. Hierdurch ergibt sich eine besonders einfache Konstruktion für die Abstandshalter und eine besonders einfache Montage.According to one further feature of the invention, each spacer comprises at least two clamping points, each cup-shaped with a wrap angle> 180 ° formed and are connected by a bridge. This results a particularly simple construction for the spacers and a particularly easy installation.
Die Abstandshalter sind hauptsächlich in Strömungsrichtung des die Außenseite der Rohre beaufschlagenden Mediums angeordnet, so dass der Strömungswiderstand der Abstandshalter minimiert wird.The Spacers are mainly in the flow direction of the outside arranged the pipes acting medium, so that the flow resistance the spacer is minimized.
Um bei möglichst geringem Strömungswiderstand eine hohe Stabilität der von außen im wesentlichen quer zu ihrer Längsrichtung angeströmten Rohre gegen Schwingungen zu erzielen, sind zumindest einige Rohre der in Strömungsrichtung des Anströmmediums aus gerichteten Rohrreihen paarweise durch weitere Abstandshalter miteinander zu verbinden. Diese zusätzlichen Abstandshalter liegen quer zur Strömungsrichtung des die Rohre von außen anströmenden Mediums und sind vorzugsweise in Strömungsrichtung versetzt angeordnet, so dass sich eine möglichst geringe Behinderung der Strömung ergibt.In order to achieve a high stability of the pipes flowed from the outside essentially transversely to their longitudinal direction at the lowest possible flow resistance against vibrations, at least some of the tubes in the direction of flow of the onflow directed pipe rows are to be connected in pairs by further spacers. These additional spacers are transverse to the flow direction of the pipes flowing from the outside medium and are preferably arranged offset in the flow direction, so that there is the least possible obstruction of the flow.
